tor cylinders whereby the motive fluid will be thoroughly broken up and vaporized and delivered to the motor cylinders in a high combustible state. a

It is another object of the invention to provide an auxiliary compression drum or similar receptacle which is connected with the combustion v chambers of the motor and in which a portion of the pressure from the chambersis stored under compression with means for connecting said 20 pressure receptacle or drum into the fuel feed tank whereby pressure is applied to the fuel in the tank to effect the feeding of the fuel and with means for connecting said pressure receptacle with the carbureter device to the end that the 25 fuel, as fed to the carburetor device, will be subjected to a blast ofthe hot compressed vapors delivered from the pressure receptacle or drum.

A further object resides in the provision of novel means for scavenging the cylinders.

80 With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accom- 35 panying drawings, wherein- Figure .1 shows a longitudinal, sectional view of the motor.

Figure 10 shows an outer end view of a cylinder.

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures, the numeral l designates an approximately circular casing having the circular front and rear end plates 2 and 3 secured thereon and enclosing the crank chamber 4. The front and rear plates 2 and} have suitable aligned bearings 5 and 6 wherein the crankshaft is mounted to rotate. This crankshaft has the oppositely arranged eccentric wrists 8. and 9 and mounted on the casing are the front and rear series of cylinders 10 and I0, respectively.

In the respective cylinders are the series of pistons 12, it which are connected to the corresponding wrists by the connecting rods i4, 15 as shown.

In the present illustration a radial type of motor is shown and on the forward end of the crankshaft is a propeller i6 and between the propeller and the casing and fixed on the crankshaft there is an air current generator I! which is enclosed by a suitable housing It. This housing has a discharge pipe l9 which is connected into a circular air manifold 20. This manifold has the branches 2| which are connected into the heads of the respective cylinders and which are controlled by the inwardly opening air valves 22 mounted in thecylinder heads on the stems 23 and the conventional springs 24 are provided to normally maintain the air valves closed. Leading outwardly from the cylinder heads are the exhaust pipes 25 which are controlled by the inwardly opening exhaust valves 26 mounted on the stems 2! and normally held closed by the springs 23. These exhaust valves are shown as exhausting into the free atmosphere separately but it is obvious that they may be connected,

if desired, into a common exhaust manifold. The numeral 29 designates a pressure receptacle. In the present instance this is shown in the form of a drum. The numeral 30 designates a pressure valves in a conventional manner.

manifold and leading from it and entering the drum there is a pipe 3|. The pressure manifold 30 is connected with the outer ends of the respective branches 32 leading out from the cylinder heads. Upon starting of the motor a portion of the air in the cylinders will be forced out through the branches 32 into the manifold 30 and thence through the pipe 3| into the pressure drum 29 and after the motor has started a portion of the gases on back stroke, under pressure, will be forced out through said branches into the manifold 30 and thence through the pipe 3| and into said drum to maintain the required pressure in the drum. The branches 32 are controlled by the inwardly opening exhaust valves 33 in each cylinder head, said valves being fixed on the outwardly extended stems 34 and normally held closed by the pressure springs 35.

There is an intake manifold 36 which is connected into the respective cylinders through the intake pipes 31 which are controlled by the inwardly opening intake valves 38 in the cylinder. These valves are mounted on the outwardly extended stems 38 and are normally held closed by the pressure springs 43.

The-numeral 4i designates an auxiliary fuel supply tank into which motive fluid is fed from a main supply tank, not shown, through the supply pipe 42. A conventional pump may be employed for feeding the motive fluid into the auxiliary tank 4|, if desired. A delivery pipe 43 leads from the auxiliary supply tank 4| and is connected into the valve casing. 44 and this valve casing is connected to the cross-connection 45 as more clearly shown in Figures 1 and 4. This cross-connection 45 encloses a mixing chamber 4 and leading from the valve casing 44 into the mixing chamber there is a tapered valve seat 41 which is controlled by a needle valve 43 having a threaded connection with the outer end of the casing 44 and having a surrounding 'stufllng box 49 as shown. A controlling arm 50 is attached to the outer end of the needle valve 43 as more clearly shown inFlgures 1 and 2.

The mixing chamber '46'is connected into the intake manifold 35 through a tubular connection upper end of the valve 51 has an overturned arm' 53 which is connected with the arm 53 by means of a cross-link 53, pivoted to said respective arms. Any suitable valve controlling device, accessible to the operator, may be employed for shifting the arm" and thereby controlling the valves 48,-

51. The outer end of the cross-connection 35 may be closed by a suitable, removable plug 60. The valve casing 56 is connected into the mixing chamber 46 by means of a tubular connecting nipple 6|. This nipple 6| has a tapering nozzle passageway 62 therethrough thus forming a blast nozzle whereby the pressure vapor will be discharged at high velocity into the mixing chamber 4i.

The numerals i3, 34, ii and G6 designate, respectively, the rocker arms for operating the The cycle of operation of a cylinder is illustrated in Figures 5 to 8, inclusive. With the motor turning in 2.

clockwise direction the firing order'of the series of cylinders I0 is one, three, five and seven and the firing order of the series of cylinders II is six, eight, two and four. Upon starting of the motor there will be suflicient air under pressure stored up in the drum 2! to force the fuel into the cylinders and thereupon the motor starts firing. Conventional ignition means as 61 are provided for igniting the charges. Thereafter a portion of the gases, on power stroke, will be conducted from the combustion chambers of the cylinders into the drum 29 to maintain the required pressure therein. The fuel in the auxiliary tank 4| will accordingly be subjected to the pressure contained in the tank 29 and will be thereby forced through the said pipe 43 and through the ,valve seat 41 into the mixing chamber 46 and the mixture will pass thence through the Venturi passagewayv 52 into the intake manifold 38 and thence to the cylinder but after the air intake and exhaust valve have been closed. When the motor is stopped and the valves 48, 51 are actuated to closed position the pressure fluid in the drum 29 will be trapped and maintained under pressure, the valve preventing the feed of the motive fluid from the fuel tank 4|. 'Upon start ing the motor the valves 48, 51 should be actuated to open position to permit a resumption of the feed of the motive fluid. Should the pressure in the drum 29 be reduced on account of leakage, the pressure will be restored in the drum 28 while startingthe motor, the pistons l2, l3 acting as a pump for that purpose. As the motive fluid is fed through the mixing chamber 45 it will be constantly subjected to a blast of the hot pressure vapor from the druin 29 through the connecting nipple which connects the valve casing 56 with the cross-connection 45, the fluid passing through the tapering nozzle passageway 62 being discharged at high velocity through the mixingchamber. The motive fuel will also be fed under pressure and the fuel vaporized in the chamber 45 will be forced through the Venturi passageway 52 and will thereby be further vaporized forming a mixture which will enter the intake pipe 36- and will be delivered into the motorcylinders in a highly combustible state and after the cylinders have been scavenged and filled with clean air.

The cylinders will be thoroughly scavenged by the air forced inwardly through the branches 2| and discharged outwardly through the exhaust pipes 25 and clean air will be supplied to each cylinder after each explosion.

When the piston is near the end of its back stroke the exhaust valve 26 is fully-,opened and the air inlet valve 22 begins to open and is fully open when the piston reaches the end of power stroke, as shown in Figure 5. As the piston begins compression stroke the air valve and exhaust valve both close and the fuel mixture valve 38 opens and again closes when the piston reaches approximately the position shown in dotted lines in Figure 6. The valve 33 is at this time closed. Thereafter all valves close and the piston continues to moveto the limit of its compression stroke as shown in Figure 7. After the compression stroke and as the cylinder moves backwardly, as shown in Figure 8, the pressure valve 33 opens and air under compression, upon original starting of the motor, and thereafter a portion of the hot vapors, the products of combustion, pass through the branch line 32 to thepressuredrum 23.
